Its main function is to protect the core from the erosion of the surrounding environment, and at the same time, it can also play the role of insulation, prolonging the service life. The cable sheath is prepared by extrusion with a cable extruder. The cable sheath extruder utilizes the pressure and shear force generated by the rotation of the screw to fully plasticize and uniformly mix the material, and then forms through the die.
